Specification of Letters Patent. I

Patented Nov. 7, 1 916.

Application filed september 25, 1907, Serial No. 394,584. RenewedMai-ch30, 1916. Serial No. 87,875.

To all whom itmay concern:

Be it known that I, EDWIN WALKER, a citizen of the United States,residing in Erie, in the county of Erie and State of Pennsylvania, haveinvented a certain new and useful Phonograph, of which the following isa specification.

This invention is a phonograph the carrier for. the record of which issimultaneously rotated and given a traveling movement with respect to arelatively stationary reproducer.

According to one embodiment of this invention, the record-carrier ismounted on a traveling carriage, and with said carriage and 1 therecord-carrier are combined devices forsimultaneously rotating therecordcarrier. and for feeding the carriage at a proper rate of speed,the movement of'the carri ge being a slow one as compared with the speedof the record carrier.

The carriage, its operating devices, and the driving means for therecord carrier are simple and durable in construction, and operate withvery little friction, wear and perceptible noise.

A broadly new feature of the'instrument consists of means forsimultaneously adjusting the reproducer and controlling the motor whichoperates the record-carrier, whereby records may be removed and replacedwithout scratching or multilating them by the stylus of the reproducer,the latter being 1 supported firmly in position and out of the Wayduring such interchange of the records.

The reproducer which it is preferred to emplo is of the characterdisclosed in my prior atents No. 805,544 and No. 805,600,

- as well as in a copending application Serial -No 394,586, filed oneven date herewith.

For the purpose of conveniently 'carrylng the reproducer and the entiremachine, it' is preferred to provide a portable case in ,which the motorand working parts of the machine are installed'permanently, said casebeing provided with compartments for the reception of the reproducer aswell as of a number of records, etc. A 7

As disclosed in the aforesaid Patents and I application, the reproduceris provided with a plurality of styli, and it is adjustable lengthwisefor. bringing either stylus into engagement with a record. 9

A According to the present invention, the reproducer is,. preferably,equipped with means for supporting. it firml in either of severaladjusted positions. aid support- 1ng means restrains the reproducer fromsldewise movement in a horizontal plane,

but permits free movement in a vertical plane. One element oftheaforesaid supporting means is foldableinto compact relationwith thereproducer when the latter is dismounted and packed in-the aforesaidportable case, whereby the reproducer may be easily removed or replaced,as desired.

In the accompanying drawings, I have illustrated one practicalembodiment of the invention, but the construction shown thereinis toflbeunderstood as illustrative only,

1and not as defining the limits of the invenion.

Figure 1 is a side elevation showing the portable case in an openposition and the parts of the phonograph adjusted in position ready foruse, the combined horn and reproducer being supported in a raisedposition with respect to the record carrier or mandrel, in order that acylindrical record may be placed readily'on said carrier or .80-mandrel. Fig. 2 is a vertlcal cross section through the ,portablecasing, showing certam parts of the'machine in longitudinal sectlon andside elevation, the combined horn and reproducer being-illustrated inend elevation. Fig. 3 is a plan view of the port able casin and thephonograph, the horn and repro ucer being removed. Fig. 4 is a verticalsection on an. enlarged. scale and in the plane indicated by the dottedline 44 of Fig. 1 looking in the direction of the arrow, the reproducerand horn being omitted. Fig. 5 is a vertical section taken on the line5-5 of Fig. 4 looking in the direction of the arrow. Fig. 6 is adetailcross section through a part of the carriage, showing the feedshaft and the feed-lever ortraveler which cooperates with said shaft,the plane of the section being indicated by the dotted line 6-6 of Fig.2. Figs. 7 and 8 are views in side and end elevation illustratinganother embodiment of the invention. K For convenience in transportingthe machine and. the records, I have shown a porpartments, B, B, B Thecompartment, B, is adapted to receive the Combined horn and reproducer,C, when the latter is dismounted from operative relation to a record.The

' 5 compartments, B,-B provide forthe storage of a number of records,and between said compartments is a motor casing, D, which contains theoperating parts of the motor whereby the record is rotated on its axisand moved endwise with re'spect to thecombined horn and reproducer. v IY Within'the compartment, B is mounted 01; secured a baselplate, E, thesame extending crosswise of the portable'casing, A, at one end thereof.This base plate is provided with longitudinal parallel rods, 6, e, whichform a track for a' slidable carriage, Fl

' Said carriage is shou .1 as consisting of the members, 7", 7, each ofwhich is cast in a single piece of metal, substantially in theform-represented in Fig. 6. The members of the carriage are joinedrigidly together by appropriate longitudinal tie-rods, f, and saidmembers are provided with the arched or curved upper end, P, each beingformed with a depending perforated lug, 7, see Fig. 6. At the respectivesides of the carriage are grooved rollers or'wheels, e, 6 the rollers,e, beingadapted to ride upon the rods,

1 e,of the track, while: the rollers, 0 ride 'against the underside ofsaid rods, whereby the carriageis limited to sliding movement \on thetrack, and the'vibration of said car 'riage is minimized by theengagement of the rollers with said track. The carriage supports arecord carrier, G, herein shown as a tapering mandrel for the receptionof cylindrical records. Said mandrel is provided with a shaft, G, whichextends lengthwise of the carriage and is journaled in the aperturedlugs, F, of the members, 7, composing said carriage. The shaft, G, ismounted I for rotation freely within its bearings of the carriage and itis moved endwise with said carriage, whereby the mandrel, G, is adaptedfor both rotary and 'endwise movement.' The mandrel, G, is mounted on ashaft, G, and this shaft is provided with a longitudinal groove orkey-way, g, in w hich 5.0) works a spline or feather indicated bydottedlines at g in Fig. 2, said spline or feather serving tooperatively connect a driving pu1-' ley, G with the mandrel shaft. Thisulley is held from sliding with said shaft, fitting it loosely between apair of upstand- I ing posts, 71., which are made'fast with the" bedplate, E. It will be understood that the pulley, G is driven by themotor for the purpose of rotating the shaft, G, and the mandrelthereombut as said shaft and mandrel are moved endwise by a feedmechanism, to bepresently described, the pulley, G, is restrained by theposts, it, from sliding with said shaft, whereby the pulley whichimparts rotary motion to the mandrel has recent? a fixed or,predetermined relation to the motor. r I

I designates a feed shaft which is journaled in appropriate bearings, eof the bed "plate, E, said shaft being preferably below the .mandrelshaft, G, parallel thereto and extending looselythrough the members, ,7,of the traveling carriage. It is preferred to provide a coarse malethread, 23,011 this-feed shaft, and with said :male thread engages a'feed lever or traveler, I. Said] traveler is pivoted at one end, asate" to the'carriage, see Fig. .6, and the leveris notched at a pointintermediate of its ends, as at i where- I noted that the carriage,while actuated by the spring, is ,controlledby-the feed shaft, and thisshaft is'loperatedbvthe motor, the func- "tions of said motorbeing,mainly, to rotate the mandrel and, the feed shaft.

It is evident, that the' lever, to which the spring is attached, may belifted by hand from engagement with the screw shaft,-for the purpose ofvmoving the carriage without hindrance from the'shaft in. one directionor the other, thus permitting the carriage and the record to be easilyand quickly returned to a starting position.

The feed shaft, 1, is provided with a pulley, P, which is adjacent toand below the pulley, G on the mandrel shaft. Said pulleys, G I, aredrivenby belts, G 1 see Fig. 3, said belts being operated by pulleys GI, of the motor, see Fig. 4.

p The combined horn and reproducer, C, is

of the shape more particularly shown in Figs. 1 and 2, said horn andreproducer being constructed as disclosed in my prior patu ents and in acopending application filed on even date herewith, Serial No. 394586.The element, C, (is provided with a plurality of styli, c, which arefixed'to the base of the reproducer, near the closed rear .part thereof,and said reproducer-is mounted for adjustment longitudinally of thecasing, whereby either of the styli, 0, may be brought into gigagementwith a record on the mandrel,

he reproducer is provided at its front 5 portion with a supportingbracket, J, the upper part of which is connected pivotally at, j to aplate, j, the latter being fixed to a rib, c, at the mouth portion ofthe'reproducer. This supporting bracket is foldable chine, and isadapted to'be stored-within the compartment, B, of the portable case;The supporting bracket is adapted togbe'fitted adjustably on theportable case, '-A,' .byf .ny

suitable means, butit is preferred-to'c on-I struct said su'pportin holdthe reproducer,

bracket in a'; wayto ducer, while permittin' it"to Vibrate on the"horizontal axis afi'orde by the piyot,'j. As

I are attached or made-integral with a plate,

shown in Fig. 1, the supportingbracket, J, is provided. with .alongitudinal socket, 1' in which 'is adapted to be" fitted eitherof thesupporting pins or sterjns,.J'. 'SaidstemS J ,'and thelsteins arejspacedon; said plate at intervals corresponding to the intervals betweenthestyli, 0-. The plate, J is fastened to the casing,A,in a suitableway, and the upper: edge of said plate projects above the correspondingedge of the casing. The bracket, J, is providedwith an angular foot--piece, J which is forked as'at 7' so as to embrace the projecting topedge of the plate,

J When the reproducer is mounted for the bracket, J, to fit on the firststem}, J,

the forked foot, J engages with-the plate,-

J and the first stylus, c,is adapted to rest ,on the record of themandrel, G. To bring the second stylus into position for operation,

the bracket, J, and .the reproducer are lifted so as to withdraw saidbracket from the first stem, after which the bracket may be slipped overthe second stem, J and locked into position for the foot to again engagewith the plate, whereupon the secondflstylus is in position forcoiiperation with the record. This adjusment of the reproducer and itssupporting bracket may be performed to bring the third stylus intocooperative relation with the record, but it is to be noted that ineither of the several positions of the reproducer the foot, J of thebracket is adapted to engage with the plate, J for holding thereproducer against sidewise movement. if j h In F igs: 4 and-5 of thedrawings, 1 have shown one form .of motor which has been found to givegood results in practice, but it is to be understood that I' donotintend to restrict myself to the use of any particular form of.motor, f r the reason that said motor may be modifi d wide limits. Asshown, the driving spring,

. K, is anchored at oneend with-in thecasing,

D, but the other end of this springds'made fast with a disk or drum, is,or said, end. of the spring may be-secured rigidly .to th maindrivmg'shafhL; Said shaft'isinoun I .ed in suitablebearings-withinthecasing, D, a and inone' -sideof the -c 'asing,D., or-the port ablecase,A, is an opening, Z,.which is'infrom vibration side- I wise, and at thesame time, secure the ne'ces I i sary' longitudinal adjustment; oftherepro--, rigidly secured the driving pulley, I wh1chwoperates'the feedshaft, I, at the required the belt, (i for rotating the mandrel is car-.

ried by the shaft, N, and the. shafts, L, N,

and changed within alinement with the end portion of the. main shaft, L,whereby a key or crank maybe inft'roduce'd through said opening andengage f'with anend portion of the shaft, L, for the purpose of turningthe latter in order to place the driving spring, K, under tension. As isusual in the art, a detent mechanism,

'{such-as apawl and ratchet (not shown) :is employed for vhOIding'rthedriving spring 1 against unwinding. on this shaft, L, is"

speedg Said'shaft, L, is provided with a geangp, which meshes with apinion, m, on I a counter shaft, M, and this counter-shaft is'providedwith' a gear,- n, which meshes with: a pinion,' n,, onashaft, N.g'aidshaft is provided w1th agear,- o',.-- hav'mg intermeshincrengagement with a plnion, 0', on a.,"'

short shaft operating the centrifugal fgovernor mechanism, 0, the latterbeing jof'any suitable orpreferred construction. Said governor operatesa brake disk, p, with which is adapted to engage a suitable form of.regulator for cbntrolling the speed of the motor, and consequently thespeed of the pulleys which operate to impart the sliding and "rotarymovement to the mandrel, G.

The driving are so arranged for operation that the carriage, F, will bemoved endwise at the required speed and the mandrel, G, will be operatedat a different speed, whereby'the record is moved endwise androtatedsimultaneously to operate the reproducer.

One of the important features of my new machineis a combined reproducersupport I U i and stop mechanism for .themotor, said device operating tolift the r'eproducer from the record simultaneously with thestoppage' ofthe motor, and vice versa, said mechanism operates to start the'motorsimultaneously with the adjustment of the reproduce'r into ous devicesmay be employed for performing this function, but in Figsi and 5ofthedrawings, I haveshown a simple and efl'ecf I tive means for thispurpose. A brake lever, P, is arranged-within themotor'ca'smg, 1D, andsaid lever is fulcru'med at p on a a depending arm, 9, which carriesthe'brake ward to the top portion, (i ofthe motor casing, and said end,{of the lever is conpulley, G, which operates coiiperative relation withthe record. Varit I fixed 1 bracketlarm, p; ;The lever is provided withnected'b'y a. screw, r, 'witha slide, R, elatif ter resting;upon thetop, d, of said motor casing. i, Said-,slide' isiprovidedon its nnder-"side ,withs jafri b, 13f arranged to work-in a s1dt,.. r bf the motorcasing, a d the slide is equipped with a bent arm, S, which extendsupwardly" from the slide, and is preferably porting said reproducer in araised. position '15:

curved to forma seat on which is adapted to rest the underside of thereproducer C. The slide is movable in the slot, 2, of he motor casin andthe range ofadju'stment'of the slide 1s regulated by a stop, 8, which isfitted in the slot, 1*, and is adaptedto be fixed at ,difierent pointstherein by a screw, 8, said stop being in the path of the slide, R. The

slide, B, may, be moved in the slot, 1' for the purpose of adjustingtheseat, S, below the reproducer, C, for thepurpose of supwherein thestyli are above thepath of the record, substantially as shown in 1,"said reproducer turning on the pivot, j, when the rest, S, is thrustbeneath it. Said inward movementof the slide and seat turns the lever,P, on its fulcrum, p, and moves a the brake shoe, q, into engagementwith the g brake disk, 3),- whereby the inward movementjof the slide,,R,simultaneouslybrings theseat,.S, intoengagement withthe reprogovernor,O, and the motor. The reproducer is adapted to be supported by the seat,S, in a position whereln the styli, 0, are above'the record, and as themandrel, G, is

at rest, a record may be withdrawn from said mandrel and a new recordplaced thereon, such interchange of the records being effected withoutdanger of scratching or inutilating the records.

The mandrel, G, and the reproducer, C, are at right angles to eachother, said reproducer extending lengthwise of the portable case, A,and'said mandrel being moved end- -wise in a path at right angles to thereproducer. Such arrangement and operation of the parts is quitedesirable when the entire 7 machine is to be-carried or packed in aportable case, but it is to be understood that the invention is notconfined to the employment of a record mandrelrnovable in a path atright angles tothe axis of a reproducer. In Figs. 7 and 8 of thedrawings, I have shown a phonograph wherein the cylindrical end- -wisemovable mandrel is arranged in a parallel relation to the reproducer,the said mandrel being movable lengthwise in a path i' parallel to thelongitudinal axis of said re-' godu'cer. The mandrel is carried by ashaft,.

which is mounted in a carriage, F, and

' said carriage is moved endwis'e by a-feed shaft while the mandrel is.rotated from the 1 motor by a pulley, all as heretofore de-' 60 scribed.The reproducer, C, may be equipped witha single stylus, c, or with aplurality of styli, and said stylus of the reproducer is adaptedt'o restonthe record, Z, at a point located to one side of the vertical plane ofthe mandrel shaft, see Fig[ 8. This relation. of the reproducer tothemandrel prevents ducer and. applies the brake shoe, 9', against thedisk, p, for. the purpose of arresting the the stylus from'sliding inone'dire'ction ofl the record, but the movement of the reproducer in theother direction is limited by a suitable anchor herein shown as an arm,T,

one end of which is pivotally connected as at t to the reproducer, whilethe other end is pivoted at t to afixture, T, adapted to be fastened tothe motor casing, D.

The apparatus shown in Figs. 7 and 8 is operated in practically the sameway, and by the same means, as the structure shown in the other figuresof the drawings, except that the record is moved endwise in a pathsubstantially parallel to the longitudinal axis of the reproducer andhorn. In this connection attention is called to the fact that the recordmandrel is mounted on the carriage, F, for movement below and length-'wise of the reproducer and horn, and in connection with the last namedelement, I em ploy the combined support and brake. The support, S, ofFig. 8 is adapted for engagement with the arm, T, for; the purposeeoflifting the arm and the reproducer when the brake is applied to arrestthe motor, but areverse operation takes place, as heretofore,

described, when the support-and brake are adjusted,-whereby the supportlowers the reproducer on the record simultaneously with the opera'tionofreleasing the brake.
